http://seekingalpha.com/article/1751982-evs-solar-panels-and-free-lunch-sophistries?source=email_rt_article_readmore my response: While I agree w/ some points in this article, namely, "front-loading" the filth, when creating EVs or PV panels or even efficient gas-powered cars (albeit to a lesser extent), there are many incorrect assumptions. Why would I charge an EV only at night, when in a few daylight hours I can fill up w/ 300 miles range, using your Tesla example. Any excess solar energy created gets fed back into the grid, for others to use during peak-hours, hence lowering the overall need for coal-powered production. Also, even though the filth is "front-loaded," in the production of EVs/PVs, there is a break-even point, and there are PV systems in operation for over 30 years (most warranties for these system are decades long). And should we not strive for long-term solutions, cleaner solutions, than are available today, even if other less-developed countries use more coal? I'm sure you're aware of US's huge energy consumption vs. the rest of the world's, per population.
